I'm thinking I'm ready :: RHCE Checklist...
 
Hello All,

So I'm thinking I'm ready for the RHCE...

I've read Jang's book cover to cover and did all the labs. This coupled with the fact that I am a Unix Admin (Solaris/RHEL) at work, leads be to believe that I am ready to take the test.

I don't know if I'm missing something...

* I know how to use the Rescue Disk...
- Use grub-install
- Use mkinitrd
- use RPM with the "root /mnt/sysimage" option

* Set up services for basic operations... (NFS,HTTP/HTTPS, SMB, DNS, FTP , ETC)
- Set up SELinux to work with these services
- Set up the firewall to work with these services

* Set up Disks
- Using FDISK
- Use/Edit LVM
- Use/Edit mdadm
- Setting mounts in /etc/vfstab and using autofs

* User managment...
- Add/modify/Delete users
- Permissions (standard and using ACLs)
- Add/Modify quotas

* Networking...
- Setup Networking with system-config-network
- Using /etc/sysconfig/network-scripts/ifcfg-eth0

Is there anything I am missing? I'm pretty confident in the RHCT portion (all the xorg stuff) , just a little nervous about the RHCE portion ;-)

Is there anything that I am missing? Should I study on something I am not listing?

To be perfectly honest...I am not too good at PAM modules...I just NEVER had to edit them in the field...hopefully that doesn't bite me in the butt during the test!

Any help would be good...

Well the bulk of the actual work is in that "setting up services" bit, which isn't detailed at all well. make sure you're happy with apache, squid, sendmail / postfix, tcpwrappers etc...

Thanks for the tip...

I guess there is no _true_ way to know until I take the test :-)

I haven't scheduled it yet...but I will update when I have taken the test!

Good luck!

How do you:

- Set up SELinux to work with these services
- Set up the firewall to work with these services

Depends...

Let's say you want to use HTTP...on the firewall open ports 80 and/or 443. Then check if your doc root of your site has the "httpd_sys_content_t" set on the directory...

You know how to use SELinux effectively within a real world environment?

Code:

setenforce 0
All you need to know.

Ha Ha! :D

That's part of my "How To Set Up a New Server" documentation at work...actually come to think about it....I also have this set up in my ks.cfg file...

Code:

selinux --disabled
Don't know how much I'll use SELinux after the RHCE test...maybe for a credit card processing server...

Just compare your this checklist with RHCE Prep Guide made by Red Hat itself, and you'll know what's remaining to learn or if you're ready for exam!

So selinux is not so popular in real life.

What about iptables for http?

YES

Those _are_ important in real life...

The "bulk" of the work in real life is web serving...so iptables and http/https is REALLY important...

are you going to take just the exam? its advisable to get at least the rapid track course - since you have quite a grasp of RH administration, the course is a good reviewer (and would give you an insight what you'll have for the exam).

acid_kewpie 11-27-2008 02:31 AM

My take is that the fast track course is a waste of time. if you pass the exam with having only done that course, then you could have passed it without ding it at all, as it's too fast a track to really *learn* much of use. That said, if your employer is paying, go for it.
